I believe everyone on our company's existing series of scanning products are very clear, we all know, the company's indoor single-color products generally 1/16 scan, indoor full-color products have 1/8 scan, 1/16 scan, 1 1/2 scan, 1/4 scan, 1/6 scan, 1/6 scan, 1/8 scan, outdoor and Asian outdoor single color products are 1/4 scan, outdoor full color products are static scan, Scan and so on. So what does scanning mean? How do I understand 1/2 or 1/4 scans in my product?
Usually, we in a certain display area, the number of lines lit at the same time the ratio of the entire area lines, known as the scanning mode.
For example, we use outdoor sticker S8 (1/4 sweep) products:
Under normal circumstances, when lit this product, we can see with the naked eye, it is the beginning of the whole plate lit together. If we look at it from the point of view of its working procedure, it is not. It is lit in 4 steps, with 4 lines lit up at a time. Because of the relationship between the naked eye and the eyes, so give us a false impression that it is lit with the whole board. This phenomenon is called 1/4 scan mode.
Now on the market, LED display scanning methods have two kinds of static scanning and dynamic scanning.
How to understand static scanning and dynamic scanning?
In general, from the drive IC's output pin to the pixel implementation of "point-to-point" control, this is called static scanning, the implementation of "point-to-column" control is called dynamic scanning;
